GDAX, Coinbase’s digital currency exchange, has been leading the rally all day. The price on GDAX is currently about $500 ahead of other Western Bitcoin exchanges. The likeliest – and most bullish – explanation is that Coinbase is the easiest way for new Bitcoin investors to get involved. Consequently, when GDAX leads the charge as it has today, it probably means new “retail” investors are fueling the rally.

Meanwhile, as CoinDesk reports, Ron Paul wants to know: would you take $10,000 in bitcoin, cash or something else?

The former U.S. Congressman from Texas is currently holding a poll on his official Twitter account that asks in which form they would take $10,000 from a “wealthy person”. The catch: you can’t get rid of it for 10 years.

Paul – who earlier this year called for the U.S. government to “stay out” of bitcoin – put the question to his more than 650,000 followers, asking if they would take $10,000 in the form of bitcoin, dollars, gold or 10-year U.S. Treasury Bonds. The result thus far – one hour remains in the poll at press time – indicate that of the more than 70,000 responses, 54 percent expressed support for bitcoin.

Gold took the second-highest amount with 36 percent, followed by a mere 8 percent for the 10-year bonds. Just 2 percent indicated that they would take the Federal Reserve Notes if offered.

A wealthy person wants to gift you $10,000. You get to choose in which form you'll take the gift. But there's a catch: You must keep the gift in the form that you choose, and you can't touch it for 10 years.

Speaking with TheStreet in October, Paul conceded that he’s no expert on cryptocurrencies (back in 2014, he argued that bitcoin wasn’t “true money”). That said, he voiced his support for cryptocurrency in the most recent interview, arguing that it lends credence to the emergence of alternative currencies against the U.S. dollar.

“Money is a bubble that never pops,” he said at yesterday’s Token Summit II in San Francisco.

He told attendees:

“It’s a consensus hallucination.”

And speaking to the newfound attention to bitcoin, Ravikant said people are interested in growing the wealth that they have. With most savings accounts returning zero these days – as central banks conduct what Ravikant called their “grand money printing experiment” – the general public is looking for alternative places to store their money and watch it grow.

Additionally, Coindesk notes that the former chairman of the U.S. Federal Reserve, Alan Greenspan, has joined the many financial luminaries to recently criticize bitcoin’s value.

Speaking to CNBC, Greenspan compared bitcoin to that of an early American form of money called “Continental currency” that came into use in 1775 and had become worthless by 1782. The paper-based legal tender was used at the time of the American Revolution and was not backed by a commodity such as gold.

Noting that bitcoin will likely suffer similar fate, Greenspan said that a “significant share” of Continental currency was still used to create “real goods and services,” even though it had no ultimate worth.

He continued:

“Bitcoin is really a fascinating example of how human beings create value, and is not always rational … It is not a rational currency in that case.”

Greenspan’s comments come as the value of a bitcoin is soaring beyond most expectations, having gained thousands of dollars in value in the last two days.
